The Allies are trapped on Mistmurk Mountain and the God-Emperor guards every way of escape. There’s only one chance for freedom: for demure little Maelys to confess to a crime she has not committed, though if she does it will turn her friends against her. Nish, Flydd and Maelys have no choice but to venture to the Tower of a Thousand Steps, on the frozen Isle of Noom. There they must seek aid from the implacable sorcerer – the Numinator.
But on that tragic journey, they will uncover a greater and more deadly secret.
